Applications of 619-72-7
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Key intermediate in the synthesis of the anti-tuberculosis drug para-aminosalicylic acid (PAS) | Reduction of the nitro group to an amino group, followed by diazotization and hydrolysis |
| Pesticides | Benzoic acid-type precursor for synthetic pyrethroid insecticides (e.g., cypermethrin, deltamethrin) | Hydrolysis to p-nitrobenzoic acid, followed by esterification, acid chloride formation, and reaction with alcohols to construct the pyrethroid backbone |
| Dyes | Diazonium component in the synthesis of azo dyes and triarylmethane dyes | Used as a diazonium salt precursor; after diazotization, coupled with aromatic amines or phenols to form colored compounds |
| Organic Synthesis | Preparation of important aromatic amine/aromatic acid derivatives such as p-phenylenediamine and p-aminobenzoic acid | Selective catalytic hydrogenation of the nitro group; or hydrolysis of nitrile to carboxylic acid, followed by further functional group transformations |
